QUOTE: "The stone age and prehistoric age were tottaly different."---Sen
Actually, prehistory is technically defined as "history unrecorded by writing, often because prehistory happened bfore writing was invented". The Stone Age is still classified as prehistoric (even though NO dinosaurs were around then, having died out 65 million years earlier), but it might not be, because drawing, a cousin of writing and perhaps its ancestor, was around during that time. It is interesting that many of us havbe to think you have to have dinosaurs or some other prehistoric beasts around to have prehistory itself. In fact, our planet Earth spent practically most of its life in what we now call prehistory, and covered in that vast super-era of history were millions of species of plant, animal, insects, fungus, and single-celled lifeforms. I hope you understand.
BTW, I'm not sure acid rain killed the dinosaurs, because it would have also killed a lot of animals that are still alive today, such as crocodiles, turtles, lizards, snakes, tuataras (cousinsof the present-day lizards, which nowadays live in New Zealand), birds, and so on and so forth. But a castatrophe of some other kind COULD have been responsible.
